Final answer:
The core area is the most heavily traversed by primates over the course of the year as it contains essential resources and is often defended against others.
Step-by-step explanation:
The student asked about which of the following ranging areas is the most heavily traversed by primates over the course of the year. The options were Core area, Home range, and Territory. Among these, the core area is typically the most heavily traversed part of a primate's home range. This is because the core area contains critical resources such as food, water, and shelter that are essential for the primate's daily survival and comfort. Primates spend a significant amount of their time in the core area, often defending it against other groups or individuals. In contrast, the home range includes the core area and all the areas that the primate might visit over the course of the year but may not actively defend or use as consistently. A territory refers specifically to the area that a primate or primate group actively defends against others. While there may be significant overlap between these terms depending on the context and the species in question, in general, the core area receives the most heavily traversed traffic throughout the course of the year.
